ppmtoyuvsplit - convert a portable pixmap into 3 subsampled raw YUV
files
ppmtoyuvsplit basename [ppmfile]
Reads a portable
pixmap as input. Produces 3 raw files basename.Y, basename.U and basename.V
as output. These files are the subsampled raw YUV representation of the
input pixmap, as required by the Stanford MPEG codec. The subsampling is
done by arithmetic mean of 4 pixels colors into one. The YUV values are
scaled according to CCIR.601, as assumed by MPEG.
